I believe you are looking at a worn out master die, not class 6 doubling.
Class 6 doubling is a 'stretched' doublng where letters, especially those toward the outer edge of the deisgn, become stretched, or distended through the hub flattening out attempting to impart its design onto improperly softened dies. The result is normal hubbings, then hubbings with a pancaked out design. This is the only class of doubling that doesn't necessarily always look like doubling due to the general lack of 'separation' between the primary and doubled devices.
